From 1efdc57d4293cc8365911d2096cc80f0a2cbbbcb Mon Sep 17 00:00:00 2001 From: Chao Yu Date: Fri, 22 Aug 2025 22:50:08 -0400 Subject: [PATCH] f2fs: fix to call clear_page_private_reference in .{release,invalid}_folio [ Upstream commit 6779b5db90c5b925293f7ccc5ed5336c5b24ed50 ] b763f3bedc2d ("f2fs: restructure f2fs page.private layout") missed to call clear_page_private_reference() in .{release,invalid}_folio, fix it, though it's not a big deal since folio_detach_private() was called to clear all privae info and reference count in the page. BTW, remove page_private_reference() definition as it never be used.
